GHRP-6 and mod GRF, 100mcg of each 3x a day is the way to go with peptides IMO.
I used them both for a short time before, and used G6 alone for awhile. G6 alone at 125mcg twice a day gave me great results actually, but the mod GRF definitely increased the results.
That being said, the only AAS I have noticed affecting my anxiety/depression would be tren and oral tren. It gets worse if I am running a shit ton of test, or if I take a ton of orals/suspension pre-training.
I had very mild depression before starting my self trt/cruise blast protocol. It seems to have went away for the most part and I generally have a more positive outlook. This may not be the case with everyone though.
Anxiety has always been terrible for me. When I went on just test, I would actually say my anxiety improved some, or at the very least didn't get worse. The only compound I have used (and I have used most in my brief time on AAS) that affects my personality in any significant way is tren. When I add in tren my anxiety gets bad. Paranoia has gotten to a point it is semi-dangerous, although I have finally learned to control it and just tell myself its in my head. When I am on tren, and take some oral tren+suspension pre-workout then I am pretty pissy the rest of the day, and my paranoia is worse. Especially if I smoke weed post workout to help my appetite. The paranoid, bad high is almost always the high I experience.. usually 2 large pizzas later I am fine again though.
That being said, I know guys who had worse psychological issues than myself prior to using, and they seemed to improve or have no effect at all. I have never saw anyone without pre-existing issues have any personality changes, except cases I believe to be placebo effects where the guy believes in "roid rage" and all that bullshit. I have a very hard time AAS would cause any real psychological issues unless the person was already very close to going off the deep end to begin with.
To Kakarat... AAS are not addictive in my opinion, and they definitely aren't a gateway drug to all that other shit. Because AAS are black market commodities in most countries, often AAS users gain access to other drugs, however I believe very few partake in them. If they do, its usually not from an addictive standpoint. Many use opiates and weed to further enhance performance, which I strongly believe can be done if you know how, considering I have done it myself.
Then again, I am not a doctor. I am just a nerdy juice head, who has a blatant disregard for my health and pretty much just cares about putting more weight on the bar.
